Dropbox announces Webhooks

I just got an announcement from Dropbox about an hour ago. For some reason, it got sent to gmail spam folder...

It was announced 2 weeks ago. Prior to that it was in beta for many months...

I just got the email myself. I wasn't aware they did something like this, but it's a feature I'd always wanted since I'm working on a small/potentially big project and it's something I considered using if it existed (trying to be cheap right now).
